I was quite pleased with the general look of this, but am now wondering if it should have been bigger, somehow, given that this was the hill that withstood the downfall of Beleriand....

The design is loosely based on the fortress of Masada. But I think if I'd reduced the size of the detail (eg, given it more towers but made the towers smaller) it might have been hard to get the whole thing in the picture. It was only drawn on A4.

In the physical version you can see that they are on a rope strung from the tower to the building beneath, which is slanting and slightly curved by the wind that is tugging it sideways - but it's hard to make out that detail in the digital version.
